#
# Run the ffmpeg command line shown.

# Version 1.00 - inital working release as a command line variant

# Version 1.07 - remove offending newline from URL download string
# Version 1.08 - change HTML defined characters '&apos;' and '&amp;' to an apostrophe and an ampersand
# Version 1.09 - modify $init_url to reflect SBS server change
